B.46 WRITEHEX Create User Data Logs

The writehex command/log allows you to create logs which contain user data.

The writehex command allows you to supply user data for the writehex log. Upon receipt of the writehex command, the receiver generates a writehex log to all destinations which have been configured to send writehex logs with a log writehex onnew command.

All of the supplied arguments are echoed in the generated writehex log.

If written to a logfile, the previous argument is overwritten to indicate the file offset (from the beginning of the file) of the previous writeb or writehexb log. The first record in a logfile has this field set to 0.

length specifies the number of bytes supplied as data.

data is up to 1024 joined hexadecimal pairs if the writehex command is issued in ASCII, and is 1024 bytes in a binary writehex message.
